Why can't overriding methods throw exceptions broader than the overridden method?
...ption, but SQLException does not.
This is because of polymorphism:
A a = new B();
try {
a.foo();
} catch (IOException ex) {
// forced to catch this by the compiler
}
If B had decided to throw SQLException, then the compiler could not force you to catch it, because you are referring to th...

:: (double colon) operator in Java 8
... would call the reduce method using Math.max(int, int) as follows:
reduce(new IntBinaryOperator() {
int applyAsInt(int left, int right) {
return Math.max(left, right);
}
});
